TOBACCO-HILLER.

SPECIFICATION forming part of Letters Patent No. 494,621, dated April 4,1893.

Application filed December 27, 1892. Serial ITO-456,410. (No model.)

To all whom it may concern:

Be it known that we, ABRAHAM F. BOW- MAN, CHARLES H. OHMART, and ALBERTA. ALLEN, of Dayton, county of Montgomery, State of Ohio, have inventeda new and useful Improvement in Tobacco-Hillers, of which the followingis a specification.

Our invention relates to new and useful improvements in the class ofagricultural implements known as tobacco hillers.

The object of the invention is to provide means for scraping up asuitable amount of earth from the ground, into small hills, at certaindistances apart, to suitably level the top of the hill so collected, forthe introduction of the tobacco plant. In the attainment of this object,our improvements have reference to a combined hoe and patter, adapted tobe operated up and down, and to the horizontal beams pivotally attachedto the shaft of the driving wheel, and to the rear end of which, the hoeand patter are attached; to a segmental rod attached to the under sideof the beams, a crank rod rigidly attached to a rear shaft at rightangles to the segmental rod, and adapted to describe a circle in whichit alternately comes in contact with the beams and the segmental rodthereby depressing or raising the hoe and patter, and means for rotatingsaid rear shaft all of which will be fully described in thespecification and claims.

The drawings herewith presented illustrate our invention, and arereferred to in the following order, reference letters thereon indicatecorresponding partsin the several views.

Figure 1. is a side elevation of our improved tobacco hiller. Fig. 2. anenlarged vertical section, on the line 0cx of Fig. 1. Fig. 3. anenlarged detached, detail of the sprocket chain with laterallyprojecting wings. Fig. 4. a plan view of the entire machine, with one ofthe handles broken to avoid obscuring any of the essential features.Fig. 5. an enlarged side elevation of the rear part of the beams.

Referring in detail to the drawings, A denotes the driving wheel whichtogether with sprocket wheel (a) is rigidly secured to a main shaft B,pivoted to the horizontal beams O-C; these beams are suitably braced,and support at their rearward ends, the combined hoe D, and patter D,with the brace rod 19 and also the horizontal segmental rod 6, one endof which is provided with a cross piece a adapted to be secured to theunder side of the beams, and the other end, to the block fwhich securesthe rear ends of the beams together;

this rod is one of the essential elements of our invention, and willbehereinafter described in operative relation to other parts.

hh denotes drag rods pivoted to the forward ends of the beams, and E-Erepresents the handles of the machine, pivoted against the said dragrods at front, these rods extend rearwardly on an incline and have theirrear ends rigidly secured to runners or slides hh. An arched frame 11encircles the rear parts of the machine and is rigidly secured in avertical position to the runners h'h and the handles E-E.

In the rear of the machine, a shaft, F is pivoted to the frame d,whereon it has the bearings as shown in Fig. 2., a crank consisting ofrod I, side flange pieces I and I are rigidly attached to this shaft ina position to bring the said flanges in sliding contact with the sidesof the beams when the crank is rotated by the shaft, and therebypreventing the rod I from lateral movement. A. sprocket wheel a ispivoted to one end of the rear shaft, and dogs 'L'i are rigidly attachedto said shaft on either side of the sprocket wheel; the ends of thesedogs project beyond the periphery of the wheel, and are adapted to becaught by the wings j-j projecting laterally from the chain it, as thesaid chain travels around the sprocket wheels. The projecting pieces orwings 7'-j release the dogs after the latter have rotated the shaft Fsufficiently to cause the crank rod I to make two thirds of a revolutionor thereabout wherein the said rod comes in contact with the lower sidesof the beams, raising them and therewith the hoe and patter from theground, after which the crank rod falls by gravity against the segmentalrod e and thereby presses the hoe to the ground, and presents the dogsin a position to be again taken around by the approaching wings.

Fig. 2. shows the dogs in a position preparatory to being caught by thelaterally projecting wings on the sprocket chain, and in this View isalso shown the crank rod out of contact with the beams, the hoe restingupon the ground and supporting the rear ends of the beams. It will beunderstood that only the beams and the parts rigidly attached theretoare subjected to the action of the crank. A hill thus raised is jumpedby the hoe when the crank rod I engages with the beams, and in itscontinued rotation again with the rod 6 to raise a succeeding hill, themoment the hoe makes a succeeding contact with the ground, therearwardly projecting patter presses the crest of the previously raisedhill, and flattens it to an extent suitable for the introduction of theplant. The distance between the hills is regulated by the spaceintervening between the wings on the chain. I11 the drawings the chainis shown set for hills two feet apart. The handles are not aifected bythe vibrations of the beams yet they add pressure to the hoe while thesame is in contact with the ground. Should it become necessary to drivethe machine without operating the hoe and patter, the crank may beprevented from turning by placing a pin or wedge between the flanges andthe under side of the beams.

Having described our invention, what we claim, and desire to secure byLetters Patent, 1s

1. In a tobacco hiller, the combination with the main shaft,of thevertically reciprocating beams provided with a combined hoe and patterrigidly attached thereto; and subjected to a reciprocating motion,thereby, substantially as described.

2. In a tobacco hiller, the combination with the main shaft and drivingand sprocket wheels mounted thereon, of vertically reciprocating beamscarrying a combined hoe and patter secured at right angles to each otherand rigidly attached to said beams, a segmental rod also attachedto saidbeams, a rear shaft rotatably attached to an arched frame, a sprocketwheel pivoted to said shaft between dogs 'i, a crank rigidly secured tosaid shaft, and the means for rotating the same to bring said crankalternately against the beams and the segmental rod, substantially asdescribed.

3. In a tobacco hiller, the combination with a carrying frame consistingof vertically reciprocating beams pivoted to the shaft of the drivingwheel, and drag rods with runners pivoted to said beams, of asegmentalrod, rigidly, and a rear shaft, having a crank rod, pivotally, attachedto said beams, a combined hoe and patter secured at right angles to eachother, and rigidly attached to the reciprocating beams, the means asdescribed of rotating said rear shaft, to raise and lower the beams,substantially as described.

4. In a tobacco hiller, a frame consisting of beams O C pivoted to thefront shaft, and drag rods and runners pivoted to said beams and thearch 01 attached to said runners, of a combined hoe and patter D and D,and a segmental rod attached to said beam, and a rear shaft attached tothe arch (Z, with means for rotating said rear shaft whereby the beamsare given a reciprocating motion to lower and raise the hoe and patter,as herein described.

In testimony whereof We have hereunto set our hands this 15th day ofDecember, 1892.
